Presentations Overview

The effect of vegetation on sediment dynamics gains increasing attention for coastal protection. To assess these effects, laboratory experiments with live or artificial vegetation are widely applied. A major challenge in such experiments lies in the measurement of bed level and bedforms since standa...

This paper presents the results of the analysis carried out to design a low-cost passive energy absorber for the multidirectional spectral wave tank of the IMARES-UCR group. Once built, reflection coefficient measurements were performed for different regular wave conditions to determine its behavior...

Understanding marine dynamics, particularly in coastal areas with high wave activity, cannot be achieved without physical modeling. However, when it comes to downscaled physical wave modeling, accurately recording wave data becomes a challenge, especially near coastlines where disturbances are commo...

A new methodology to investigate air-water flow properties in highly unsteady flows

The capabilities and performance of the newly built wave generation and passive absorption system in the Coastal & Ocean Basin (COB) wave tank are investigated. Together, both systems are designed to achieve high-quality wave fields inside the measurement volume of COB. An assessment of the accuracy...

Single layer randomly placed armour units are used in many rubble mound breakwaters around the world. For these armour layers, breakage of armour units due to rocking could be a major damage mechanism, but no good methods exist to evaluate and quantify rocking. The aim of the study is to quantify th...

This conference contribution introduces and validates a laboratory-scale measurement method employing photogrammetry techniques. With the rapid advancement of computer vision technology, it is possible to improve the limitations of traditional wave gauges and better describe temporal and spatial wav...

The presence of marine pollutants such as marine plastics has increased significantly over the last decades and poses a major environmental problem, in both the coastal and offshore area. The fundamental fluid mechanics processes associated with marine transport are often not resolved in large-scale...

The decomposition of the water level into incident and reflected wave components is usually a necessary step in numerical or flume studies, as most design variables (overtopping, run-up) are linked to the incoming wave characteristics. Thus, utilizing an appropriate wave reflection analysis is criti...
